i have a 91 dakota with a 3.9l v6. and i have a 68 318 with 10.5:1 pistons, chromolly rings, fireball cam, 40 thousandths of the heads, edelbrock low rise intake, edelbrock 600cfm electric choke, custom painted elite series valve covers....anyway i plan on putting this motor in this truck over christmas and wanted yall opinion.

thanks

 

do it. since that 318 isnt fuel injected you may have issues though.

 

crap, crap, crap, i want one

 

what do you mean since the 318 isnt fuel injected i may have problems?

 

When you say "40 thousandths of the heads" do you meen decked or milled down. I got mine .030and I had trubble lining up the intake with 30 thohow was 40 tho. did you bore out the engine? Did you deck the block? I decked my block .015

 

The heads were milled down and yes it was hard to put the heads on. and the intake took some time to. The block was decked. No i didnt bore the engine out. Its still a 318.

 

how much you deck the block? Why was it hard to put the heads on. The only trubble would have been the intake.

 

i dont know how much the block was decked. i meant the heads were easy and the intake was hard to put on. my bad

 

i mean that the 318 is carbed so it wont use a computer, your truck wont know what to do. the engine and transmission have to "talk to each other".

 

.040" is borderline for stock pushrods. You might run into low cylinder pressures. If so, you'll be using adjustables.

And FWIW, chromoly rings are not worth it. They take 4-EV-R to seat. I'll never use them again after the blowby issues I had on my 360. They actually let enough past that I hadcrank casedetonationfrom fuel vapor buildup and blew the valve covers off on a hot start.
